Ordering number: EN 14108 | Monclithic Digital IC No.1410B | LB1403N Series 5-Dot Red/Green LED Level Meter | Use AC level neters such as VU meters. . DC level meters such as signal meters. Features and Functions . Capable of generating a bar-display for input voltage with 5 LEDs. + Operates from either AC or DC input voltage because of on-chip rectifier amplifier. - Lighting levels remain stable to line regulation because of on-chip voltage reference. . LEDs are driven by a constant current ; stable to line regulation, . Power supply voltage range is wide (3.5 to 16V), for a wide range of appli- cations. . Five types of ICs constitute the series with various lighting levels of the LEDs and driving currents. - SEP=-9 pin package and fewer externally connected components result in snaller space requirements on the circuit board. - Low noise at LED lighted mode LB1403N Series Type No. fer lighting sensitivity Comparator level Conatant LED current LB1403N 85 oVrms typ +6dB,+3dB,0dB,-5dB,-10dB 15 mA typ LB1413N 105 mVrms typ 1.67Vc3,1.33V03,o3,0.67703,0.33Vc3 15 mA typ LB1423N 85 mVras typ +6dB,4+3dB, 0dB,-5d5,-10dB 7 mA typ LB1433N 105 mVrms typ 1.67c3, 1.33V03, o3,0.6703, 0.33003 7 mA typ LB1443N 85 wlrns typ +64B,4+30B,0dB,~6dB,-12dB 15 mA typ Equivalent Circuit Block Diagram and Pin Assignment : amp + !
